The Indictment
The money at the center of the case came from the women who worked at the shop.
On Thursday, October 1, 2026, the Special Investigation Department of the Osaka District Public Prosecutors Office indicted a 49-year-old man from Kyoto's Yamashina Ward at the Osaka District Court on charges that include violating the Corporation Tax Act, the Yomiuri Shimbun reported. Prosecutors also indicted the company, Shinko, a limited company (yūgen kaisha) based in Otsu, Shiga Prefecture, that runs a soapland. Yomiuri described the man as its former de facto manager.
The indictment was zaitaku kiso: he was charged without being taken into custody. Prosecutors have not said whether he admits the allegations.
What Prosecutors Allege
According to the indictment, between 2021 and 2024 he hid income by leaving the money collected from the soapland's workers out of the company's miscellaneous income, among other methods. The result, prosecutors say, was about ¥87 million (roughly $580,000) in unpaid corporate and other taxes.
The case was first made public on September 29 and 30, when the Osaka Regional Taxation Bureau announced that it had already filed a criminal complaint. The Asahi Shimbun, the Sankei Shimbun, the Kyoto Shimbun, ABC TV, Yomiuri TV and Biwako Broadcasting (BBC) all reported it, and their accounts largely match.
- The amount. The bureau says about ¥249 million in income was concealed over three business years that ended in January 2024. Yomiuri TV, which rounded the figure to ¥250 million, said the unpaid tax broke down into about ¥61 million in corporate tax and ¥26 million in consumption tax.
- The method. All six outlets said fees collected from the women were kept off the books. Asahi, the Kyoto Shimbun, Yomiuri TV and BBC said the company also booked fictitious expenses. Sankei reported that the money had been collected from the women as "sundry fees."
- Where the money went. Several outlets said the man appears to have used the money to buy securities and crypto-assets. Sankei reported that most of the undeclared income went into purchases in his own name.
- The shop. Asahi and Yomiuri TV identified the business as a soapland called "Amuāju" in the Ogoto Onsen district.
The bureau filed its complaint with the Otsu District Public Prosecutors Office on February 26. Yomiuri reported that the case was later transferred to Osaka, where the special investigation unit took it over.
The reports give slightly different dates for the period covered. Yomiuri TV and BBC put it at February 2021 through January 2024. The Kyoto Shimbun cited January 2022 through January 2024. The difference may reflect how each outlet counted the company's fiscal years.
Why the Women's Fees Matter
Ogoto Onsen sits on the western shore of Lake Biwa. It is one of Japan's best-known soapland districts and draws customers from Kyoto and Osaka.
Soaplands are licensed as store-based sexual-services businesses under the fūei-hō (the Businesses Affecting Public Morals Regulation Act). The industry has long kept a formal distance from the baishun bōshi-hō (the Anti-Prostitution Act). One way it does so is by treating the women less as employees on a payroll and more as individual workers who pay the house for rooms, supplies and other charges.
That arrangement puts money flowing from the workers to the operator, and it can be easy to leave off the books. This case appears to turn on that flow. Prosecutors do not allege that any customer revenue went missing. They allege that the fees taken from the women never showed up as company income.
A Pattern of Enforcement
The Ogoto case comes amid a busy stretch of enforcement against the store-based end of the industry. On September 30, police in Ehime Prefecture re-arrested the managers of a soapland and a health parlor in Matsuyama's Dogo district. They alleged that the managers had signed contracts with women to have them engage in prostitution. In Tokyo, investigators have spent the year pursuing the "Natural" scout group and the shops it is accused of supplying.
Tax cases are a separate route to the same businesses. The cash-heavy industry has long drawn attention from Japan's regional taxation bureaus. A criminal complaint is generally reserved for large, deliberate evasion, and the ¥87 million figure here is well within that range.
What Happens Next
The case now goes to trial at the Osaka District Court. Under the Corporation Tax Act, an individual convicted of tax evasion faces up to 10 years' confinement, a fine of up to ¥10 million, or both. The fine can be raised to match the amount evaded. The company can also be fined separately.
Neither Shinko nor the man has made a public statement in the reports cited here. He has been charged but not convicted, and he is presumed innocent.
